GREASE RETAINER FOR AUTOMOBILE REAR AXLES.

Application filed November 19, 1924. Serial No. 750,874.

This invention relates to lubricant retaining means adapted for use with the rear axle of a standard Ford automobile, or one of similar construction, and the, objects of the invention-are to provide an inex f pensive device which may be easily applied and which will effectually prevent the inbrie-ant from'within the difi'erential housing fronnrunning along the rear axle housing and finally dripping out. of and over the rear wheels, or getting on the brake drums. The invention is carried out by ,the construction shown in the accompanying drawings, and in which- Figure 1 is an approximately -fu-ll size longitudinalsection of a portion of the rear axle housing and outer roller bearing shell for the Wheel of a Ford automobile withmy device in position within the axle housing and surrounding a; broken length of the rear drivingaxle 'so as to show its relation thereto.

Figure 2 is a perspective view of my device apart from the automobile structure included in- Figure 1.

' In the drawings 1 represents the rear axle,

' housing of a Ford automobile, 2 a portion of the outer split shell of the roller bi'iaringv for the wheel end of the axle, 3 shows a portion of the rear axle as it would be positioned in the housing, 4 a sheet metal tube being part of my invention and surround ing the axle and with an enlarged cup-like portion 5 at the outer end tightlysup rounding the inndr end ofthe mllenbearing shell 2. I A

To pro'yide' room forthe rim of.- this on portion between thebearing shell and the housing 1, the shell is reducedaslightly 'around its end preferably by grinding around the outside to form a short neck 2 thereon prefer bly. slightly tapered and the cup. is fitted tightly thereover.

'lhe tight fiti aided by the expanding tend:

cncy of the split shell holds the cup tightly in place, yet it is easily applied to the shell and pushed into place within the housing with the tube 4 projecting over the'shaft. At the inner end of the tube 4 is a leather or other flexible collar or boot 6 secured. to the end of. the tube preferably by cementing or sewing through the tube as indicated. at 7, or both, and the boot is reduced slightly at its inner end 8 to form an opening adapted to fit snugly over the rear axle and is re siliently held thereagainst by a strap 9 stitched at 10 to the boot and having a ring 11- in each free end connected by a small spiral sp'ing 12 The lea er boot arrangement as described forms a tight but yielding joint sealing the inside of the tube from the axle housing space so that no oil can run along the houscomprising a tube-adapted to go overthe axle within the axle housing, tube being provided at --one end with pa cup shaped fiange"embracing the inner .scribedforthe rear. axle of an automobile said I.

end .of the roller bearing outer shell and provided at its other end" with ialflexible boot yieldingly 'el'nbracing the axle; said boot being stitched at onegend to the tube and provided with eontr'actinganeans at the other end.
